 For this session we are honored to welcome Dr. **Andrew Hoffman**, the Faculty of Social Sciences data steward, who will speak from his vantage point about data management, its institutionalization and professionalization in contemporary academic research, its relation to ethnography---but especially what it looks like in practice and why it can be a helpful skill even if you don't intend to become an academic researcher.
 
 **No tutorials this week.**
